PL/ITFORM USED IN CHARGING R DISCHARGINGBETORTS m GAS -BENCHES SPECIFICATION forming part of Letters Patent No. 760,640, dated May 24 1904.

- Application filed March 7,1904. Serial No. 196,914- iNo model.) I

To all whom it may concern.

-'Be it known that I, KERR MURRAY MITCH- ELL, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented new and useful. Improvements in Platforms and Appliances to be Used in the Charging or Discharg-' ing of Retorts in Gas-Benches, of which the following is a-specification.

My invention is'for the improvement ofla platform and of its appliances to be used in the charging and in gas-benches.

In my Patent No. 433,802, dated August 5, 1890,I employ a mere platform or car on wheels, but having no means for moving the platform or car.

My present invention, among other devices, includes special means for easily moving the platform or car by the operator standing on the same either forward or backward to or from the front of one bench of retorts and discharging of the retorts also whereby when the work of drawing and charging has been completed he may also move of retorts to be charged or discharged. Fig.-

3 is a plan of the platform or car. I

A is a cast projection from the car platform or plate B and which serves to support a standard 0, firmly secured or braced on the platform-p1ate B. I

D is a shaft extending up throughthe projection A of the platform and through a proper support E near the top of standard 0. This shaft carries a bevel-gear c on its top and a similar gear 0 on its lower end. The gear 0 engages with a bevelgear, f .on a crankshaft f, provided with a crank f 2 for operating the vmechanism.

At both sides of the platform are side I boards Z Z.

It will be seen that all the mechanism above the car is upon the projection A, thus leaving the whole of the-car-floor clear and unobstructed, and that the operator can perform all his duties from the platform, as also the moving of its car from one bench to another and from any position or place to another at will and without his leaving the platformc'ar or going down into the pit or pushing the car.

i What I claim as new in' apparatus for charging and discharging of retorts in gas-benches having a pit extending in front of the bench is as follows:

1. In combination with awheeled platformcar for spanning the pit, a projection from the platform and supporting a stand shaft, a hand-crank for operating this shaft, gearing engaging said shaft to a sprocket-wheel, and a sprocket-chain from said Wheel to a sprocketwheel secured to a driving-axle of the car. 2. In combination with the platform or car, the standard C thereon, the operating-crank, and its shaft and bevel-gears supported in said standard, the upright shaft D carrying bevel-gears 0, 0 at its ends, the bevel-gear c engaging withthe'gear 0 and the sprocketwheel sprocket-wheel 7c, and chain 7', serving to actuate the car-wheel as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

KERR M. MITCHELL.
